165438+1October 1 1, the New York Mercantile Exchange crude oil futures prices soared due to the US Department of Energy's report that domestic crude oil reserves fell more than expected, and closed above the price of $83 per barrel on Thursday. Appendix: Conversion method of petroleum volume and weight unit 1 Conversion of volume and weight units Density P must be introduced into the conversion of volume and weight units. The density pt of crude oil and refined oil refers to the oil weight of P tons per cubic meter at a certain temperature. The conversion relationship is: the volume of one ton of oil = 1/p m3, which is equivalent to the number of barrels of one ton of oil = 1/p * 6.29 barrels (oil). Divide the density by 6.29, and find the conversion coefficient formula of how many barrels of oil 1 ton of oil equals. This conversion coefficient is related to the density of oil products, and there is a reciprocal relationship. For example, the density of Daqing crude oil is 0.8602, and the density of Shengli crude oil depot is 0.9082, which are: Daqing crude oil conversion coefficient =6.29/0.8602=7.3 1, and Shengli crude oil conversion coefficient = 6.28. If the density of a certain gasoline is 0.739, the calculation result is: 1 ton gasoline equals 8.5 1 barrel; The density of a diesel oil is 0.86, and the calculation result is that 1 ton diesel oil is equal to 7.3 1 barrel. And so on. Table 1 lists the conversion factors of tons and barrels of conventional oil and ordinary crude oil at home and abroad. The price of gasoline, coal and diesel in the American market is in cents/gallon, which can also be converted into dollars/ton by the above formula.
